    Thanks,

    It was a simple fix in the end The display was blank all the time and with no power light the unit looked dead but in fact the unit was working. This fix was to replace C19 near the display. many of the model 5's were fitted with a 33 uf 25v capacitor which breaks down after a period of time. Replace this with a higher voltage version, The Bose Service Bulletin recommends a 63v. I have schematics and a service manual now..

    Thank you! I had two problems with our Bose. One was a broken trace where the power connector was attached to the PCB - easy to find and fix. But the display still didn't work but the tuner, amp and everything else di if you blindly navigated through the settings. Changing C19 fixed the display. Thanks again.

    Hi DAvid:

    My LS5 is dead too. I'm waiting to have courage enough and schematics to start opening it. Any help will be much appreciated.

    Best regards.

  • jay_kallberg Jul 18, 2008

    Have the same thing, but cant for the life of me find c19?

  • Anonymous Jul 18, 2008

    I have the exact same problem, system functions but no fluorescent display. I've opened it up and found C-18 and C-20, but no C-19. Is it on the same circuit board as the display unit, or on the larger, main CB, where C-18 & 20 are located?

  • Hercdriver Jul 19, 2008

    OK, after some research I found that this unit has a different circuit board arrangement and there is no C-19!

    The culprit is instead C-17, located on the main board, left hand edge. It's 33ufd, 67v just like the C-19 reported on the other posts.

    I was unable to find a 100v cap so put in a 250v rated one. It's a little fat, but it fits ok and the unit works like a champ now.

    I did this repair for a friend. He said he contacted Bose and they charge a flat $250 fee to fix it. This seems to be a very common failure, it cost me 85 cents for the part. (And $2.00 for the gas to go get it.)

    I have the same problem with my Bose lifrstyle 5 music center as all of you do. It just dose not work, I picked mine up at a garage sale and was told that everything worked. It seem's that it has no power to the radio/cd player. I have read some of the post's about this problem but I know nothing about the inside of a circut board or any C-19. So is there any way I could use the 5 sets of cube speakers and the ( what looks like a big sub-woofer ) and hook it up to my new LCD HDTV with out buying one of the new lifestyle bose units. I only paid $200.00 for all of the speakers, but if nothing works its not much of a deal.

  • Lilypad555 Sep 03, 2008

    Hi,



    I do have the same problem with this bose stereo, no power, I checked the adapter is fine. Stereo is dead. The radio was playing and then just died.

    Does anyone have the schematic? What should I test next?

  • jack383 Sep 07, 2008

    I have power to the unit the cd spins the display is not working but if I plug in a headset and can hear the cd,radio and tv. The unit does pop through the speakers when I switch from aux to video or radio. If you this is the c-19 problem which it sounds like please let me know and more info on location inside of unit Thanks Jack

  • craftsmen22 Sep 15, 2008

    My display in the Lifestyle 5 System is dead, too. As I read I should
    change the C19 but in my System I cant find a C19. On the lift lower
    side is a C16.

    I try to display a picture I shot.

    Thank you.

  • Jimbo1857 Nov 30, 2008

    Hello, I also have a Lifestyle 5 that is dead, There is voltage going into the power supply section but I am not reading any voltages at the -12, 5, 10V Test points. Does anyone have a circuit diagram of the Power supply section of this unit? Thanks, Jim

  • robby-h Dec 04, 2008

    I have a similar probem.

    Initially the display died and you could not see anything, however there was power to the system as i could get sound from both the aux and video outputs.

    something else seems to have died recently though and i am unable to get any sound at all which leads me to believe the system is completley dead. ( no power at all)

    Does anyone have a sugested fix to this and/or some sort of diagram to help me fix it?

  • Eric Grodsky
    Eric Grodsky Dec 07, 2008

    How do you open up the Lifestyle 5 unit to make a repair? I can't find
    a way to take it apart. My problem is the unit doesn't turn on
    sometimes. I end up unplugging it and replugging it in at the power
    strip, then eventually it works. My guess is I have broken solder joint
    at the power socket of the mains unit.

    Thanks
    Eric


  • e7navy Dec 30, 2008

    to: Eric

    L84THSKYI had the same intermittent power problem on my Lifestyle cd 5
    . The part at any electronic store cost about $1.25 to $1.50. Gas cost more to drive there. Bring your ac power adapter for a good match. The socket solders onto the PC board but be careful not to drip solder everywhere. Only two of the prongs are used. The side prong only help support the connector.

I just went through a similar problem. Everything on the LifeStyle 5 receiver worked fine but no display. Mine is the version "2V" as shown on the serial number label on the bottom. I just replaced the C17 capacitor with a 47uF / 35V one from Radio Shack. For those of you who have been searching for a solution you've probably noticed that for the other console version you'll either have to replace the C16 or C19. For myself on the "2V" version it was the C17.

Note, I have never really done anything electrical like this before and it IS possible to do yourself (actually helps if you have a second set of hands at times).

Supplies from Radio Shack -

  1. 25W soldering iron ($8.79)
  2. Copper desolder braid ($3.99)
  3. 1/2 oz rosin core solder ($2.19)
  4. 47uF 35V capacitor ($1.19)

Here's what I did....

1. Remove the 4 screws on the back panel with a philips head screwdriver.
2. Remove the main cover (non-cd side). Use a small flathead screwdriver to push in the 3 gray tabs on the back panel and lift up so that it prys open toward the front of the unit. Take this main cover off.
3. Remove the cover on the cd side. Use that small flathead screwdriver to push in the 2 black tabs on the back panel and lift up so that it prys open toward the front of the unit. Take this cd cover off. Both top covers should now be off so you're looking at the circuit boards.
4. Remove the top circuit board. It is just held in by a few tabs. Note, I didn't disconnect any wires, ribbons, etc. I just removed the circuit board from the tabs that keep it secure and let it rest loosely on top.
5. Remove the bottom circuit board. I found this to be the trickiest step and needed an extra set of hands to hold up the top circuit board while I worked my fingers around the bottom circuit board to release it from the tabs. I also used pens (hey, at least I'm honest) as levers to keep the bottom circuit board from falling back down and getting re-secured by the tabs. Part of my problem was not recognizing there was an additional tab in the middle of the circuit board holding it down. Just be patient and keep working it. Probably took me like 10-15 minutes just to get this board removed from the tabs. Again, like the top circuit board, I didn't disconnnect any wires, ribbons, etc. I just removed the circuit board from the tabs that keep it secure.
6. Remove the C17 capacitor. Flip over the bottom circuit board and double check to make sure you're about to remove the correct capacitor. The C17 is located near the bottom left of the circuit board. (Someone else gave me the tip to make sure that when I put in the new capacitor I had the proper polarity. I'll revisit this in the next step, but at the time I was about to remove the existing C17 I just put a mark on the outside of the capacitor so I knew how it was aligned on the board. I used copper desolder braid and the soldering iron to remove the solder from the existing capacitor. I then just pulled the existing capactor out and the holes in the circuit board looked clear.
7. Install the new C17 capacitor. I noticed that the capacitors had a different color vertical band on them. Right or wrong, I used this as a guide for me to determine the polarity when installing the new one. I just put the new one in the same way as the old one (with respect to where this different colored band was and the mark I had made on the old one) and pulled the leads through the holes in the circuit board until it seemed tight enough against the circuit board. I bent the leads back (but not broken off) to hold it in place while I soldered the connection. Once I finished soldering the connection I cut off the excess from the leads with wire cutters.
8. Test the display. You don't need to re-secure the circuit boards to test it out. I believe I just flipped it over and connected the FM antenna and the AC power cords to their respective connections in the back and it worked!
9. Reassemble the console. This was much easier than the disassembly and was essentially the steps above in reverse order. Just put the bottom circuit board back in and secure it with the tabs (including the one in the center). Then do the same for the top circuit board. Put the cd cover back on until it snaps into the tabs. Do the same for the main cover. Put the 4 screws back in and you're done! Good luck!

    Hi, you need to keep the uF the same and increase the voltage (V). Whatever you had, say 33uF, then a replacement HAS to BE 33uF, but you should increase (or kep costant) the voltage (V), not decrease it.

I had the same problem and just fixed it using David_77's advice. The difference was that my PC board was a newer revision level so the capacitor that needed changing was C17. It was the only 33uF/63V capacitor on the board. There was no visible damage to the cap, but it had degraded to a value of around 7uF. In the picture posted by craftsmen22, C17 is shown as the bottom-most capacitor on the left side. Thanks for the advice David_77!

Hello and thanks for the help. I just replaced my C16 33uF 63v to a 47uF 35V capacitor. i can now see the display but the parts of the display that is not supposed to be turned an i can see at about 50% brightness. In other words I can see everything (cd, video, tape, disk, random, Am, fm, random, etc.) all at the same time. I think the 47uF 35V is too strong. Can anyone recommend an alternative. Should I just try and find an original 33uF 63v replacement?

C19 on mine. Rather than easter egg around, I used a multi-meter on volts AC range and checked all the electrolytics. C19 had 13 VAC on it, while all others were 1 volt or less. Didn't have a replacement 33uf 25V handy, but I did have three 10uf 25V. Three in parallel is 30uf. I actually prefer the lower brightness of 20uf, so I only installed two. Not a bad day overall. Purchased the whole system with subwoofer and two satellite speakers on Craigslist for $100. Works perfectly now. Now I only need a cheap bluetooth adapter and I'm in the modern era.

I had the same problem with no display and found this thread (thanks for the info!). In my case, it was the capacitor that needed changing was C16, 100uF/25v. I replaced it with 100uF/35v I found at Radio Shack. Now I have the display back.

The only problem I still have is, once it's turned off, it doesn't remember the radio station it was on before. Is this normal?

As far as I know, schematics for Bose systems are not available outside of Bose. Check for the typical rpoblem areas: Fuses, shorted diodes, open primary winding on the transformer, etc.

Thanks for all of the information..Still took a lot of thinking..My system is up and running perfectly. I fixed the display problem very easily. The speaker output...and the R428 resistor problem was another fiasco though. The PDF file you sent of the bottom of the main circuit board wasn't opening correctly so I had to figure out from the description of the output connector to the resistor...what baffeled me was the ohms on the resistor was correct. I took a 35 mm lense and turned it backwards and magnified the resistor and found that at some point someone had changed the resistor and did a poor job soldering. I carefully resoldered the ends of the resistor and wala...All is working well....If anyone else does this I have a pic of the circuit where the resistor is located. If the techs on this site need it I can send ..also when you disconnect the 3 cables to remove the circuit cards two of them are interchangable....mark them!!

Display screen led light wont come on


If the display has been gradually fading and is now unreadable, the fault is almost certainly loss of emission of the fluorescent display and it will need a replacement display module fitted (at a Bose Service Centre)
Is there any sign of characters showing in a darkened room?

If it has suddenly gone off, with all other radio features are working as normal, but prior to this the display was bright and clear, and the set has not been subjected to a fall or a sudden sharp impact of some kind, (which can crack the display module and cause it to fail) then the most likely possibilities are; a failed filament supply to the display module, a failed high tension supply rail to the display module, or loss of data feed to the display. It is also possible there may be a fault in the day/night brightness switching circuitry that has shut the display down completely. It is not possible to be more specific without seeing the unit, or even knowing which model it is I'm afraid.

Hello. get you broken power supply re manufactured at http://www.invebo.com . The parts that fail are replaced with industrial grade long-life components and if your power supply is unsafe or too far gone then they supply you a new one. Vergy green and shipping by airmail isn't too expensive.

Lifestyle 12, NO AUDIO and a DEAD DISPLAY


You are correct. The display unit is separate from the audio issue. I have tired to work on a few of these units over the years.

Bose is so proprietary in thier electronics and repair that the average electronics technician cannot service them.

Your only luck it to send the units in for service. If you are dead set on wanting the bose units then, $250 may be worth the repair charges to you.

If I was you, I would retire the Bose equipment and go to my local electronics store to purchase a different brand unit.

Bose Lifestyle 5 ~ dead display fix


Hi the fix for a dead display is a faulty capacitor. Depending upon which board version you have, you need to replace the 33 uF / 63 volt capaitor. On some units this is C19 on the display board, on other units this capacitor is mounted on the main board and re-numbered, there is only one 33 uF on the unit so you should be able to find it.
